Warning for LEDS?

[flodas]

Hey so i switched to theese new cobs 3000k verov7 around 2 weeks ago. Replacing my 2 400w hps and one mh blasting on my yard.

I have been growing for a good amount of time and im not a rookie at this. I have since a while ago noticed that my buds didint get that swelling that they use to have. two days ago in my evening watering i noticed it, small seeds in my calyxes hermies fuck me i sayd loud.

ALL of my plants are hermies they do al come frome the same mother they have not been streesed in any cirsumstances more than a LST training. My strain have never devopled any kind of hermies or whatever in harder conditions than this.

Progress in the seeds around 1.5 to 2 weeks i would say the seeds are still small green and u can pop em in ur fingers. So this make me think can it be the light switch that did make em stress out going from a high Kelvin to a very "low"? Or can it be that they come frome the same mother they maybe have thay hermie genetic? / Flodas

If you moved from HID to LED.....Didn't the temps change? Check all timers to be working properly? Have you ran this strain before? Did you change feeding at all? Nutrient, ratio by brand etc?

Something else is in play here - you have to find it.

its not the cob. i use led . cfl hps and mh . possible there are light leaks ? as dr who said these timers are total shit they break all the time . possible the light is turning on and off ?

Yes indeed the temp droped from 27 to 24 celcius but i cant imagine that would be the problem. My timers are legrand they are of good quality but sure its possible that may be the issue i will test both of the timers.
I always run big bud as my strain and have never encounterd this problem i always run the same brand. The feeding is changed i mayde another thread about it. They didint absorb the water as good as before i was watering around every 3 days and now i had to water every 7 day u think that may be the issue? Whats hekling me is that the hermies came when i switched the light that to me is an alert. But if u run cfl hps mh and led and not encounted this problem before its maybe just the clones and the mother that have the hermie gene is that possible for a plant to hermie even in perfect conditions?

OK, my point is that while the lights are new. All they really changed was environmental conditions....YOU changed some too. Nutrients! Changes to temps and RH make up-take rates change. Not the change in light source!

It's the other changes made that, combined. have caused your herming problem!

Another point to understand. Environmental shifting. Plants will shift to grow "best" in a new environment slowly. You have a strain that you have run for a long time. Many clones ago! The plant popped from the seed was grown in a different environmental condition as your growing in - guaranteed!

Over time and as you cloned and grew the strain. It "shifted" in it's structure and growth patterns to grow in the new environment as efficiently as it can.

This strain has grown that way, for a long time as you say. Now all of a sudden several changes have been made to that environment and it kind of "shocked" the plant into thinking that it was getting closer to dying then it's "remembered" from the past for this time off growth.

I suspect the 7 degree of F change that stayed constant.....is the major problem experienced by the plant over long term. The change in nutrition and RH are what caused it to fall over the edge!

So, it's no single thing that caused the herming! It was the sum total of environmental changes all at once.

i think you just have a strand that has seen better days . i have moms that were sitting in 95f hot veg now the temp is 57 to 65. veg . and i was flowering the same in the 85f way to hot for quality not by choice grow lol and now t the hottest its getting is 65 f. swinging temps 57 to 65 . no plant issues and i have some from beans going from 70f temp for the bean to hatch . to 95f veg to the 57 to 65 . no issues dr who is correct once you switch to led or cob . i do notice they use a lot less water temps are cooler . and you will notice your cob plants will ask for calmag more then they would under the hps . its time to get some thing new going . its just a coincidence when you switched your lighting . i am all over the map with lighting . i have a lot of things going on at once to find what is the best . currently i am using 3 weeks of mh then switch to hps for bulk for 3 to 4 weeks then switch to led for the cool temp .. bring out the quality . for ever switching lighting up different spectrum and shorter days. so trust me when i tell you its not the cob lighting causing this hem . how old is this mother ? is it first generation from the bean ? only get 6 months here if lucky then i start to see funky shit . but they get stressed from all the chopping off them and weak lighting kept on top to slow there growth to save electricity then they get pounded with thousand of watts when needed more from them its a tuf life for them .

Well i found the problem or the electrician did..... its a possibility of the new enviroment but most likely there is a in improper grounding and wiring in my house and the lights flickers from time to time and its on the fuse i use for my garden thanks for all the response tho / flodas
